Code Description

ICD-10 E11.65 is a billable code used to indicate a diagnosis of type 2 diabetes mellitus with hyperglycemia.

Key Diagnostic Point:

Type 2 diabetes mellitus with hyperglycemia is a chronic metabolic disorder characterized by insulin resistance and relative insulin deficiency. Patients with this condition often present with elevated blood glucose levels, which can lead to various acute and chronic complications. Hyperglycemia in type 2 diabetes can result from inadequate glycemic control, often indicated by elevated HbA1c levels, typically above 7% in many clinical guidelines. Management of hyperglycemia may involve lifestyle modifications, oral hypoglycemic agents, and insulin therapy. Complications associated with uncontrolled hyperglycemia include cardiovascular disease, neuropathy, nephropathy, and retinopathy. Regular monitoring of blood glucose levels and HbA1c is crucial for assessing the effectiveness of treatment and preventing complications. The condition requires a multidisciplinary approach for optimal management, including dietary counseling, physical activity, and medication adherence.
